The cam 33 is rotated in the clockwise direction by attaching and pulling the operating shaft 50 as appropriate, and the engagement between the pawls 24 and 25 and the ratchet 23 is released.

That is, the protrusion 37 of the cam 33 pushes the cam follower 39 in the direction away from the center of the rear shaft 5 in FIG. However, since the cam follower 39 is integral with the claw 24 and the claw 24 is engaged with the cored bar 29, the claw 24 turns around the cored bar 29 in the clockwise direction around the cored bar 29 and the ratchet tip is rotated. 23 from the teeth and disengage the pawl 24 from the ratchet 23.

By moving the cam follower 39 in the clockwise direction around the cored bar 29 in FIG. 3, the claws 24,
The movement is transmitted to the link 26 via the pin 27, and the link 26 moves in the clockwise direction against the elastic force of the spring 43. The movement causes the pawl 25 to rotate in the clockwise direction around the core metal 30 via the pin 28, and the pawl 25 is also disengaged from the ratchet 23.

Next, the braking device 60 will be described. (FIGS. 6 and 7) A U-shaped frame 61 is provided between the side frames 2 and 3 at a position where the contact point between the front roller 6 and the middle roller 9 is seen from above. U-shaped frame 61
Long holes 62 and 63 are provided in both leg portions of each, and the tips of hexagon socket head bolts 64 and 65 screwed to the side frames 2 and 3 are inserted into the long holes 62 and 63 to form a U-shaped frame 6.

A rod-shaped brake shoe 66 having a wedge-shaped cross section with a V-shaped tip is provided between both legs of the U-shaped frame 61.

Reference numerals 67 and 68 denote springs provided between the U-shaped frame 61 and the side frames 2 and 3, and when the U-shaped frame 61 moves downward by the urging force of the springs 67 and 68, the brake shoes 66. Is the front roller 6
The V-shaped tip portion is inserted at the nip point between the roller and the middle roller 9 to brake the rotation of the rollers 6 and 9. The lower ends of both legs of the U-shaped frame are in contact with notches 70 and 71 of a shaft 69 rotatably provided between the side frames 2 and 3. As shown in FIG. 7, the notches 70 and 71 of the shaft 69 are eccentric to the line connecting the center line C of the slots 62 and 63 and the center line of the shaft 69 at the rising point of the U-shaped frame 61. The top of the cross section of the shaft 69 is cut so as to form an obtuse angle (150 degrees) so as to come into contact with the V-shaped notches 74 and 75. Therefore, the shaft 69 is given a return rotational force by the tension of the springs 67 and 68 so as to pivot in the clockwise direction in FIG. A brake knob 72 is provided at an end portion of the shaft 69, and a Bowden cable 73 is connected to the end portion of the shaft 69. When the shaft 69 is rotated by pulling the cable 73, the U-shaped cutouts 74 at both ends of the U-shaped bracket 61 are provided. , 75 is the groove 7 of the shaft 69.
The brake shoes 6 are pushed up by the edge portions of 0, 71 and rise.
6 comes out from the nip point between the front and middle rollers 6 and 9 to release the braking of the rollers. By loosening the cable 73, the U-shaped cutouts 74 and 75 push down the end edges of the grooves 70 and 71 by the return rotational force due to the tension of the springs 67 and 68, the shaft 69 returns to the position of FIG. 66 returns to the nip point between the front roller 6 and the middle roller 9. Reference numerals 76 and 77 are stoppers of the brake knob 72.

In order to roll and move the drum 10 wound with a cable or the like by the carrying device 1 of the present invention, the drum 10
As shown in FIG. 1, the carrier device 1 is inserted into the acute angle portion 12 between the floor surface 11 and the floor 11. In this case, if there is a slip between the drum 10 and the floor surface 11, the drum 10 will be pushed back,
From the experience, it is desirable that the contact position between the outer periphery of the drum 10 and the middle roller 9 is within a range smaller than about 30 ° with respect to the vertical line passing through the center of the drum 10. Further, the apparatus of the present invention is set only on one side of the flange of the drum 10, but since the drum 10 is not long in the axial direction, the apparatus is applied to only one of both flanges to perform the conveying operation. Even if you go, the direction of movement can be kept constant. Then, the middle roller 9 and the drum 10 are brought into contact with each other, and the operation rod 21 is swung up and down while pressing them so as to come into pressure contact with each other. By the downward swing of the operating rod 21 in FIG. 1, the fan gear 15 rotates the drive gear 14 loosely fitted and supported on the rear shaft 5 in the counterclockwise direction. Due to the rotation of the drive gear 14, the cored bars 29, 30 planted in the drive gear 14 also rotate in the same direction. At this time, as shown in FIG. 3, a spring 43 supported between the spring seat 42 fixed to the drive gear 14 and the spring seat 41 fixed to the link 26 causes the link 26 to move counterclockwise with respect to the drive gear 14. It is biased to turn to. Therefore, the claws 24 and 25 that are in contact with and engaged with the cored bars 29 and 30, respectively, have the pins 27, which support them.
28 is moved by the pivotal movement of the link 26, the pawls 24 and 25 supported by the pins 27 and 28 are moved.
Is in a state in which the toes are engaged with the ratchet 23 as shown in FIG.

When the drive gear 14 rotates in the normal state as described above, the rotation is transmitted to the claws 24 and 25 through the cored bars 29 and 30, but the claws 24 and 25 both mesh with the ratchet 23. In addition, since the pawls 24 and 25 are urged by the spring 43 in the direction to deepen the meshing, the rotation of the drive gear 14 is surely transmitted to the ratchet 23, and the ratchet 23 is rotated counterclockwise in FIG. It Since the ratchet 23 is fixed to the rear shaft 5 with a key, the rear shaft 5 is rotated by the rotation of the ratchet 23, and the back roller 7 integrated with it is also rotated counterclockwise in FIG. The rotation of the back roller 7 is
The drum 10 which is transmitted to the middle roller 9 which is in contact with the drum 10 and which is in pressure contact with the middle roller 9 also receives a force as shown in FIG. 8 to rotate and roll in the counterclockwise direction in FIG.

When the operating rod 21 is pulled up, the drive gear 14 is rotated clockwise by the rotation of the fan gear 15. The claws 24 and 25 located in the cutout portion of the drive gear 14 also include the drive gear 1.
It rotates in the clockwise direction along with 4, but in this case the claws 24, 2
The tip of the pin 5 slides up on the slope of the teeth of the ratchet wheel 23 to rotate about the cores 29 and 30, and the pin 2
Since the link 26 supported by 7, 28 pivots and moves, the spring receiver 41 fixed to the link 26 also moves in the same direction. The spring receiver 41 is repelled by the spring 43 between the spring receiver 42 and the spring receiver 42 fixed to the notch of the drive gear 14, but during this time, the compression movement is exerted and the pawls 24 and 25 move over one tooth slope of the ratchet wheel 23. At the same place, they are engaged with each other, and the state is the same as when the pushing down of the operating rod 21 is started. During the above operation, the driving device 1 and the drum 10 are pressed against each other,
Although a force for pushing back is applied, resistance is applied to the middle roller 9 in the pushing back direction by a braking device described later, and the same braking is also applied to the back roller 7 in contact with the middle roller 9. As a result, the ratchet wheel 26 joined by the back roller 7 and the rear shaft 5 can rotate only in the counterclockwise direction. The operation device 21 is repeatedly rocked up and down to advance the carrier device 1 to roll the drum 10.

When the carrier device 1 is simply moved, the back roller 7 freely rolls back and forth unless the ratchet wheel 23 and the claws 24 and 25 are engaged with each other. At that time, by pulling the Bowden wire 53, the annular cam 33 is turned clockwise in FIG.
Is brought into contact with a cam follower 39 provided integrally with the pawl 24, and the pawl 24 is pivoted around the pin 27 in the clockwise direction to release the engagement between the pawl 24 and the ratchet 23. At this time, the link 26 also turns in the clockwise direction, but since the core metal 30 and the claw 25 are engaged as shown in FIG. 3, the claw 25 pivots around the pin 28 due to the turning motion of the link 26 in the clockwise direction. A swiveling motion is generated in the direction of the clockwise hand, and the engagement between the claw 25 and the ratchet 23 is released. This allows the carrier device 1 to be pushed back and forth.

When braking the carrying device 1, the following is done. In FIGS. 5, 6 and 7, braking is performed by inserting the V-shaped tip of the brake shoe 66 provided on the U-shaped frame 61 of the braking device into a wedge shape at the nip point between the front roller 6 and the middle roller 9. Can be hung. That is, during non-braking, as shown in FIG. 7, the U-shaped notches 74 and 75 at both leg ends of the U-shaped frame 61 are formed in the grooves 70 and 7 of the shaft 69.
1 and does not enter the groove, so that the brake shoe 66 is not in contact with both rollers 6 and 9. That is,
By pulling the Bowden wire 73 to the left in FIG. 7 during non-braking, the shaft 69 is rotated counterclockwise through the lever 72 as shown in FIG. Thereby, the groove 7 of the shaft 69
Nos. 0 and 71 contact the U-shaped cutouts 74 and 75 of the U-shaped frame 61 at the eccentric positions so that the U-shaped frame 61 is lifted and the brake shoe 66 is separated from the nip point. At this time, the Bowden wire 73 is under the tension of springs 68 and 69 that are pulled to the right in FIG.

During braking, the pulling of the wire 73 to the left in FIG. 7 is stopped, the pulling of the wire 73 rotating the shaft 69 counterclockwise is released, and the springs 67, 6 are released.
As shown in FIG. 6, the U-shaped frame 61 is lowered by the urging force of the shaft 8, the shaft 69 is rotated in the clockwise direction, and the U-shaped notches of the two leg ends of the bracket 61 are inserted into the grooves 70 and 71 of the shaft 69. Position 74 and 75. As a result, the brake shoe 66 is inserted into the nip point between the rollers 6 and 9, so that the roller 1 and the roller 6 are pushed back by the force of pressing the conveying device 1 and the drum 10 against each other. Although the brake bites into the nip point of 9 and opposes the pushing back force, the braking force is applied in the opposite direction.
The tip of the character is in the direction to be pushed out from the nip point of both rollers and braking is not applied.

[0025]

The apparatus of the present invention constructed as described in detail above directly abuts the stationary drum on the rotating roller by the same peripheral speed and feed as the speed at which the drum is about to roll, and transmits the force. When the drum is about to roll, a force can be generated in the tangential direction of the cycloid locus to obtain the rolling force. Then, in order to maintain the rolling of the drum, the same feed amount as the rolling speed can be always transmitted to the drum. Therefore, the drum can be easily carried by human power without using a large machine / device, and even if the contact position between the drum and the device of the present invention is changed due to a change in the diameter of the rotating body, The vector peripheral force with the same peripheral velocity and feed at the position is always in the tangential direction of the cycloid locus, and good rotational force can be transmitted.
